It appears that CentOS 6 no longer supports a few apache modules (mod_file_cache, mod_mem_cache, and mod_imagemap) according to their docs.

What's the best way to handle this? Just remove the references from httpd.conf, or download and compile manually?

I Was thinking of just removing and seeing if my codebase worked as expected, then if something broke, compiling manually. Hoping that I can safely remove these modules from httpd.conf and everything still works.
